Being the shallow and vain creature I am, I have always hated fat people, and fighting them is no exception.
Striking is not too bad; you're probably going to be a lot lighter on your feet, and you've already said you have a reach advantage. I've had most of my success fighting hefty lads by staying mobile and headhunting. That extra weight makes them harder to bully around the ring with kicks and body shots, but not any harder to abuse with head punching. Easier, since as I mentioned, you'll probably be lighter on your feet.
Grappling with fatties is tougher and I hate it. Getting takedowns becomes a giant pain in the ass, as does maintaining top position. Pretty much all the subs I've hit against guys with a large weight advantage over me have been from the guard or from the back, so I would train with the expectation that those are going to be your best case scenarios.

The fool thinks himself immortal,
If he hold back from battle;
But old age will grant him no truce,
Even if spears spare him.

Fat people tend to get exhausted quickly , when i first started kickboxing i was 90kg and after 5-6 punches i already fell tired , just keep moving around and kick him in the legs , that will it extra difficult to move around ;) Then you just punch him like a bag xD

Typically, on the day of the fight, I don't really change my diet much. I would just lean on the side of small regular meals versus periodic large ones, as being either hungry or in need of a **** while you're fighting is not recommended.
Typically right after making weight, I'll eat an entire meat lovers pizza and wash it down with a gallon of chocolate milk, and get back up to my pre-cut weight within the evening. But the next day, it's sort of back to business as normal with food.

do you have a corner team? I would get punched in the mouth by my coach if I went off reservation because I read something on an internet forum.

Eat pasta.

Haha true, tho After the lurking I can tell there is quite a few experienced people here.

Yeah; I wouldn't even nescessarily say lean and healthy, at least in the vernacular sense; I usually aim for small calorie-dense items; peanut butter and honey sandwhiches, meal replacement shakes, that sorta thing.

Yeah I am going to go there cause this is often an issue for me (I am sure its part of that flight mechanism that is engaged with nerves). So even if I manage to evacuate prior to a fight I often feel the need to go really badly.
It sucks.

What should I eat on said day of fight? from morning to hours before the slam cutting weight is not an issue for me so I can eat what ever you guys throw at me.

So recap, lighter on the feet, reach. I'm so excited but honestly nervous at the same time.. :)

Dont change your diet over 1 night just for a fight , eat what you gonna eat but do not eat 2 hours before the fight , i wanna go to the toilet if i eat in those 2 hours so i skip that meal and eat afterwards
